9 Effective Tips To Saving on Fridge Energy Consumption

It's now impossible to imagine life without the fridge, an appliance that's an integral part of everyday life. Since its invention in the late 19th and early 20th centuries, it has completely changed the way and length of food preservation. Today, thanks to technological innovation, it's possible to find energy-efficient fridges on the market, highly efficient appliances that reduce greenhouse gas emissions and save on energy costs. However, there's no doubt that the fridge is one of the appliances that consumes the most energy in the home.

If you think about it, your fridge is always on, consuming electricity at all hours of the day and night. How can you reduce your fridge's energy consumption? To reduce its impact on your utility bills, you can start by avoiding some small mistakes that could turn your fridge into an energy hog and follow a few simple rules. Here's how to save on your fridge's energy consumption and avoid wasting energy.

1. Be Careful About the Temperature You Set

Properly adjusting your fridge's temperature not only helps preserve food properly, but it also helps avoid energy waste and, consequently, saves money. According to the FDA's guidelines, the fridge's internal temperature (and therefore its thermostat) should fluctuate between 40°F/4°C and 41°F/5°C. But why does this save you money? Because much higher or lower temperatures cause it to work excessively, thus increasing energy consumption: it's estimated that every degree above or below the ideal temperature can increase consumption by 5-6%.

2. Keep It in Order

Did you know that even the order in which you store food in your fridge can affect its energy consumption? This is because a poorly organized fridge prevents cold air from circulating properly, forcing the motor to work harder and for longer to maintain the desired temperature, thus increasing energy consumption by up to 25%. Properly arranging food, taking advantage of the different cold zones, allows the refrigerator to maintain a constant temperature: not all areas of the refrigerator have the same temperature; usually, the middle zone remains constant; the lowest part is also the coldest, while the temperature between the side walls and the top will tend to rise. Properly arranging food also allows you to know exactly where it is, reducing the time it takes to open the door and therefore energy expenditure.

3. Don't Open It Unnecessarily

Speaking of opening and closing the refrigerator: try not to do it too often, but only when absolutely necessary, as this also impacts energy consumption. Every time you open the refrigerator door, the temperature of the compressor rises, requiring significant energy to return to the correct temperature. Therefore, good practice is not to open the refrigerator unnecessarily and, above all, to leave it open for as little time as possible when looking for ingredients to cook. The latest generation appliances are also equipped with a small alarm that lets you know when the temperature is getting too high and it's time to close the door.

4. Position It Correctly

It may seem like a small consideration, but even the location you choose for your refrigerator can affect its performance and, inevitably, your energy bill. To prevent it from overheating and consuming more energy, it's always best to place it as far away as possible from any heat source, such as stoves, radiators, or heaters. To prevent the heating coil at the back from overheating, always leave a gap of at least ten centimeters between the refrigerator and the wall, ensuring proper ventilation, which is essential for the appliance's operation.

5. Avoid Storing Hot Foods in The Refrigerator

Is the first thing you do after finishing lunch or dinner, putting the still-hot leftovers in the refrigerator? This is a habit you should learn to break: if the food is still warm, you risk wasting energy due to the refrigerator's internal temperature, which will tend to rise, and condensation, which, over time, will facilitate the formation of frost on the inside walls. It's better to wait a few extra minutes and put the leftover hot food in the refrigerator when it's at room temperature.

6. Don't Overfill (or Underfill) The Refrigerator

To ensure proper air circulation in the refrigerator, and thus the temperature needed to preserve food, it's important not to overfill the appliance. If you overfill it, the refrigerator will require more energy to function properly, and therefore, it will consume more. Conversely, an overly empty refrigerator is also bad for your energy bill, as it will waste energy unnecessarily. If you don't have enough food to fill it, you can fill the space with bottles of water and thus lighten the compressor's load.

7. Perform Proper Maintenance

An important tip for saving money is regular refrigerator maintenance: a well-maintained appliance doesn't overwork itself and, consequently, consumes just the right amount of energy without overdoing it. Regularly check the condition of the seals and, if particularly worn, replace them, as they could facilitate cold air leaks. Pay attention to the noise, too: if the appliance is particularly noisy, it may be time to repair a potential defect that's compromising its proper functioning.

8. Defrost Your Freezer Regularly

Don't underestimate regular freezer maintenance, either. Being part of the same appliance, it impacts energy consumption, especially if it accumulates ice. Excess ice builds up on the freezer walls, creating an "insulating" layer that strains the entire appliance, causing it to work harder and therefore consume more energy. If your freezer doesn't have an automatic defrost option, pay attention to the ice level: if it's more than five millimeters thick, it's time to defrost it.

9. Pay Attention to Its Energy Class

The last point is especially important if you're buying a new refrigerator: in this case, it's crucial to consider one factor in particular, more important than the appliance's capacity and aesthetics: its energy class. Since 2021, appliances have been divided based on their energy efficiency and classified on a sort of scale (the "class") ranging from "A" to "G": the higher the energy class, the lower the consumption, so a "G" class refrigerator will require more energy than a class "A" one and will therefore have a greater impact on your bills. To be fair, it's true that appliances with higher energy classes are more expensive, but this cost is easily amortized because it will save you money in the long run.
